ME System Management Bus (SMBus*) Interface
The ME uses the SMLink0 on the SSB in multi-master mode as a dedicated bus for
communication with the BMC using the IPMB protocol. The EPSD BMC FW considers
this a secondary IPMB bus and runs at 400 kHz.
this a secondary IPMB bus and runs at 400 kHz.
The ME uses the SMLink1 on the SSB in multi-master mode bus for communication with
PMBus* devices in the power supplies for support of various NM-related features. This
bus is shared with the BMC, which polls these PMBus* power supplies for sensor
monitoring purposes (for example, power supply status, input power, and so on.). This
bus runs at 100 KHz.
